Female Pattern Baldness
It is estimated that around 50% of women over the age of 65 experience female pattern baldness.
The condition results in diffused thinning of the hair on the scalp from the parting outwards, unlike male pattern baldness which occurs from the frontal hairline receding to the crown.
Female pattern baldness has a strong genetic predisposition, with indications of many genes contributing to the condition. It is not clear if androgens play a role in female pattern baldness, unlike the strong correlation to DHT and male pattern baldness.
It is reported that pattern hair loss by the age of 50 affects about half of men and a quarter of women.
Pattern hair loss is the most common cause of hair loss.
Male Pattern Baldness
male pattern baldness is also known as an androgenic alopecia and is widely thought to be caused by the hair follicles sensitivity to DHT (dihydrotestosterone).
DHT (dihydrotestosterone) is a naturally occurring substance that has been implicated in male pattern baldness. It is essentially a byproduct if testosterone, the primary sex hormone in the male body. It is believed DHT shrinks the hair follicles of men, leading to male pattern baldness.
In the male body, testosterone converts DHT, and an enzyme called 5-alpha reductase works to help this process along. Hair loss scientists are unsure of exactly how DHT impairs the hair follicle, but they do know that inhibiting it results in hair follicles that thrive instead of shrinking
Men with male pattern baldness are born with a genetic hair follicle sensitivity to DHT.
